• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Man, broken sky must really suck. Can someone familiar with it explain what is causing it to fail in so many places? Thanks.

Just posting the facts-

i was at dinner last night and there were 3 black and whites all single man units using macom/harris p7200 and m7300's.

Anyone familiar with tdma (dmr,p25 phase 2,open sky) will more than agree they all sound pretty much the same. Remember p25 phase 1 is not TDMA.

I hope the new system is as improved as they hope.

We use Harris OpenSky and it works fine. The voice quality is good. The coverage is good. I've only been bonked from the system once in the last few months.

The issue in Las Vegas is likely coverage related. I know we had to put up quite a few extra tower sites than originally planned.

The only issues with the system now that I have experienced are:
Call volume varies (call to call)
Occasionally a word will get echoed

I know Harris made major improvements to OpenSky (software related) to get the system useable. When Tyco/M/A Com had it the system just didn't work, ex:
Poor voice quality (garbled, severe echo)

Digital Stutter ( 83, can ya ya ya ya ya ya ya 10-19)

Lost calls

Radios not rx calls at the same time (even now the time delay between your mobile receiving a call and your portable receiving a call has a slight delay- it makes it difficult to talk on your radio if another radio is turned up by you). I guess it is vocoder delay because our old AEGIS/VGE radios had the delay too.


No coverage areas that were dynamic

Emergency button would trigger by itself

The system is quite usable now and I feel confident in using it. It is reliable.
